my country’s tert-butylamine production capacity is overcapacity and the industry is in decline

Tert-butylamine is a fine chemical material and an important direction for the downstream refined production of high-purity isobutylene. As an accelerator, pesticide intermediate, and pharmaceutical intermediate, tert-butylamine is currently used in the production of tire industry, herbicides, bronchitis medicines, fuels, lubricants and other products. As the main raw material of the environmentally friendly rubber accelerator N-tert-butyl-2-benzothiazole sulfenamide (TBBS), isobutylene has attracted the attention of the global industry, and the industry has developed rapidly.

In terms of application, tert-butylamine is mainly used in the field of accelerators, accounting for more than 80%, followed by medicines and pesticides, accounting for 16%. The annual output of accelerator NS in my country is about 100,000 tons, and the consumption of tert-butylamine is about 20,000 tons. There are four main production processes for tert-butylamine, namely tert-butyl urea hydrolysis method, isobutylene amination method, isobutylene-hydrocyanic acid method, and MTBE-hydrocyanic acid method. Among them, the MTBE-hydrocyanic acid method has lower production cost and better product quality. Stability is the current main research direction; the tert-butyl urea hydrolysis method has high production costs and is highly corrosive to equipment, and has been eliminated; therefore, the isobutylene ammoniation method and the isobutylene-hydrocyanate method are currently the mainstream production methods. Craftsmanship.

The output of tert-butylamine in my country is relatively low, and the current annual output is only about 18,000 tons. Global tert-butylamine manufacturers include BASF, Texaco, Akzo, Bayer, Rohm and Haas, Japan’s Sumitomo Chemical, etc. Among them, BASF is the world’s largest tert-butylamine manufacturer. Representative companies in the field of tert-butylamine in China include Luhua Tonghui Chemical, Huamei (Sanyi) Chemical, BASF Performance Chemicals, etc. The scale of production equipment is relatively small.

According to the “China Tert-Butylamine Market Feasibility Research Report 2021-2025” released, my country’s tert-butylamine production capacity is about 32,000 tons. But most devices are idle. In recent years, environmental protection supervision has become stricter, and some small businesses have stopped production and closed down, resulting in a slight increase in capacity utilization. However, due to downstream demand, production technology, environmental protection and other factors, part of the production capacity has not yet been released, and there is large potential growth space for tert-butylamine production in the future. In terms of demand, tert-butylamine is a fine chemical. Although it has a wide range of applications, its application volume is limited and the market growth is relatively slow. Therefore, there is a risk of overcapacity in the tert-butylamine industry in the future.

Industrial analysts said that as an environmentally friendly fine chemical, tert-butylamine has a high demand for application as an accelerator and will be used in medicine, There is much room for expansion in applications in pesticides and other fields. my country is one of the major producers of tert-butylamine in the world. Currently, it is mainly produced by the MTBE-hydrocyanate method, with relatively high production capacity. However, due to downstream demand and environmental protection policy restrictions, my country’s tert-butylamine production capacity utilization rate is low, and the market has overcapacity problems. In order to promote the development of the tert-butylamine industry, relevant companies need to actively expand into emerging downstream industries in order to reverse the decline in industry development.
